A multiple beam antenna system including a reflector that is at least partially parabolic in one dimension, a pair of dielectric lenses, and a pair of waveguides. Multiple received beams are received and reflected by the reflector into an orthogonal mode junction which separates signals of a first polarity...http://www.google.fr/patents/US6087999?utm_source=gb-gplus-shareBrevet US6087999 - Reflector based dielectric lens antenna system
